美国贝尔有限公司实验室研制了一种新的具有空前效力的防治鼠类的化学药物—奎宁毒素(Quintox)。奎宁毒素是一种良好的慢性灭鼠剂,具有用量小、药效长的特点,且不易变质。奎宁毒素具备抗凝剂及急性诱饵的优点,鼠类只要一次取食就可死亡。奎宁毒素的有效成分是胆维 D_2及 D_3,胆维 D_3作为毒物应用是一种创举。当适量的奎宁毒被鼠类食用时,毒物使大量钙质从骨骼进入血液,从而引起高钙血症,以致心脏障碍而导致死亡。3克的奎宁毒素就足以毒死小鼠,14克即可毒死大鼠。
The Bell Laboratories in the United States has developed a new quintoxin, an anti-mouse chemical known for its efficacy. Quinine toxin is a good chronic rodenticide, with a small amount, long drug efficacy, and not easy to degenerate. Quinine toxins have the advantages of anticoagulants and acute bait, rodents can die as long as a feeding. Quinine toxin is the active ingredient of gallbladder D_2 and D_3, gallbladder D_3 as a poison application is a pioneering work. When the right amount of quinine is consumed by rats, the poison causes a large amount of calcium to enter the bloodstream from the bones, causing hypercalcaemia that leads to death from cardiac disorders. Quinine 3 grams of toxins are sufficient to poison mice, 14 grams can be poisoned rats.
